The German philosopher and literary critic Walter Benjamin (1892 - 1940) is often seen as a writer of the Jewish Messianism, and the focus of research on him has been based on his most reknown writings such as The Work of Art in the Age of mechanical Reproduction (1935) or Thesis on the Philosophy of History (1940). Thus, most of the time only some of his work is being analysed into depth and is then classified as being messianic. But what about his not so well know work such as the Denkbilder (published in the 1920s and 1930s) which have not formed part of the Berlin Childhood Around 1900 (1933) or the One Way Street (1928)? Do they also reflect on Messianism? This paper wants to draw attention to these Denkbilder and their vision of an In-Between. An In-Between realities, focusses, vanitas, language and times allowing open spaces for thought which might also be found in the heart of religious believes. The paper wants to argue in favor of open spaces, these In-Betweens, and perhaps not to immediately search for categories to classify them as, for example, Messianism, plagiarism and so forth as Walter Benjamin himself was always trying not to go along with categories.
